GRAIN-BINDER.

SPECIFICATION forming part of Letters Patent No. 424,507, dated April 1,1890.

Application led November 30, 1888. Serial No. 292,245. (No model.)

To all whom, t may concern: Y

Be it known that I, JAMES R. SEVERANCE, of Poughkeepsie, New York, haveinvented certain Improvements in Grain-Binders, of which the followingis a specification, reference being had to the accompanying drawings.

My present invention relates to an improved Construction of thebundle-discharging mechanism described in my patent, No. 277,356, datedMay 8, 1882.

My improvements are fully set forth and described in the followingspecification and the accompanying drawings, and the novel featuresthereof speciiied in the claims annexed to the said specification.

In the accompanying drawings, representing my present improvements ingrain-binders, Figure l is a rear elevation. Fig. 2 is a side elevationtaken from the left-hand side of Fig. l. Fig. 3 is a plan showing theparts below the line 3 3, Fig. l. Fig. a represents the cam detached.Fig. 5 is a sectional view through the jointed connection between thelever and the discharger-arm. Fig. 6 is a sectional view through thejointY between the Vconnecting-rod and the support for thedischarger-arm. Fig. 7 is a front elevation of the parts in the positionthey occupy when the discharger-arm is vertical. Fig. 8 represents thesame when the discharger-arm is horizontal.

The construction of the binding mechanism is substantially the same asthat described in my previous patent, No. 345,546, and in my pendingapplication, Serial No.V 217,390. The bundle, after being bound, restson the platform and is discharged in rear of the machine by thevibrating discharger-arm A, Fig. 2, which oscillates on the pivot B, asindicated by the full and dotted lines in said figure. Thedischarger-arm is provided with the prongs or horns C C', which engageunder the bundle and lift it from the platform, delivering it, as thearm vibrates, on the stubble immediately behind the machine, butt-enddown.

The discharger-arm is operated from the binder-shaft D by means of thecrank E and the camv F, and the connecting mechanism hereinafterdescribed. It will be observed that in addition to the vibratingmovement in the vertical plane about the pivot B it is necessary toimpart to the discharger-arm an oscillating movement on its longitudinalaxis, in order to enable the prongs or fingers C C' to engage under thebundle as it lies on the platform. The vibration in the vertical planeis imparted to the discharger-arm by the crankE on the shaft D, whilethe oscillation about the axis is produced by the cam F. The shaft D,which also operates the knotting mechanism, is connected with thegearing of the harvester in such manner as to receive a single completerevolution for each bundle which is bound. This result is secured bysuitable trip mechanism and a clutch and gearing on acontinuously-revolving shaft driven from the main wheel of theharvester, as described, for instance, in my previouslymentioned cases.The binding mechanism is also operatedfrom the shaft D.

In the accompanying drawings, the frame of the binder is shown asconsisting of the rods G G', (which may be hollow,) connected togetherat their front and rear ends by the cross-bars H H. The binder-frame issupported on the frame of the harvester on suitable guides or ways,which permit its adjustment lengthwise of the grain. The knottingmechanism, which may be of any ordinary or preferred type, is supportedon the binderframe.

On the rear cross-bar H ofl the binderframe is placed one or moreupright posts I I', which support the pivot B of the vibratingdischarger-arm. The posts are preferably cast in one piece with thecross-bar, as indicated in the rear elevation, Fig. l. At their upperends they are provided with suitable journals, in which the pivot Bturns. The dischargerarm A is sustained by the vibrating support J,pivoted in the uprights I I and provided with a rearward extension a,Fig. 2, to which the connecting-rod K is attached by the universal jointb. The discharger-arm is journaled in the support J, so thatit can turnabout its longitudinal axis under the influence of the cam F, lever L,rod M, and crankarm N.V Collars d, or other suitable devices, ,securethe discharger-arm from end play. The support J may be given any desiredshape adapted to the purposes for whichV it is de- IOO -or othersuitable device.

signed. The pivot B may be either keyed or pinned in the support; or thesupport may be arranged to turn on the pivot.

On the rear end of the shaft D is secured the crank E, provided with thecrank-pin f, on which the collar t' is secured by the ring g,

The collar t' is provided with a perforated lug c, Fig. 3, to which thelower end of the connecting-rod K is jointed by the pin j. Thisarrangement constitutes in effect a universal joint between the crank Eand the connecting-rod K, which permits the swinging of theconnecting-rod as the support .I vibrates. The'other end of theconnecting-rod is attached to the arm a, on the support J by a joint,which permits movement in planes at right angles with each other, andwhich consists of the ball 7i, Fig. 6, on the end of the stud k,inserted in the arm a, and the divided socket-pieces Z Z', which aresecured in the yoke m on the connectingrod K. The bolt n serves to clampthe yoke m on the socketpieces Z Z', the opposing surfaces of which arerecessed out to lit the ball h. A universal joint b is thus formedbetween the end of the connecting-rod K and the arm a on the vibratingsupport of the bundle-discharger. As the crank E revolves, the arm A,carrying the fingers O C', will vibrate about the pivotal axis B, asindicated by the full and dotted lines in Fig. 2, so as to effect thedischarge of the bundle. The range Vof the movement'is also indicated inthis figure, as it is only necessary to cause the discharger-arm toswing behind the vertical plane in which the axis B is located to asufficient degree to insure the delivery of the bundle in rear of themachine. Any other preferred form of universal joint may be employed ateither end of the connecting-rod K.

In order to secure the oscillating movement of the discharger-arm Aabout its longitudinal axis, I apply to it the crank-arm N, whichreceives motion from the lever L by means of the connecting-rod M. Thelever L is pivoted to the cross-bar H or the standard I, as shown at O,Fig. 1, and its lower end is provided with a stud or roller p, whichengages with the cam-groove q of the cam F. The cam F is secured on theshaft D in such position relatively to the crank E and the carngroove qis made of such a shape as to impart the-requisite rolling movement tothe arm A. While the arm is raising the bundle from the platform itrests on the concave side of the fingers C C', little or no rollingmovement being impartedl to the arm A at this time, as the roller p isthen in the circular portion of the cam-groove q. During the returnmovement of the arm, however, the cam F oper-V atesthe lever so as tocause the arm to turn or roll on its longitudinal axis, so as to causethe fingers C C to engage under the bundle on the platform.- rIhe Acamiirst swings the upper end of the lever inward, causing the arm to rollon its longitudinal axis by means of the jointed connection M andcrank-arm N, so that the points of the fingers are directed downwardtoward the outer edge of the platform and outside of the bundle thereon.As the arm A continues to descend, a rollingmotion in the oppositedirection is imparted to it, so that the fingers pass inward under thebundle in position, as indicated by the dotted lines C 0', Fig. l, tolift the bundle from the platform when the arm rises. The cam-groove qis given a suitable shape adapted to produce the rolling motion in onedirection and vthen in the other, as represented in the enlarged view,Fig. 4. The connections between the upper end of the lever L and thedischarger A are built with universal joints,

so ast-0 permit the relative movements of the parts. As the crank E andcam F are rmly secured on the shaft D the movements of thedischarger-arm are always properly timed relatively to each other. Theuniversal-joint connections between the lever L and the discharger-armare conveniently formed, as represented in theacco'mpanying drawings.Thus on the upper end of the lever L is fitted a collar r, free torevolve thereon, having on one side a lug s, to which the connecting-rodM is pivoted by a pin t, Fig. 3. To secure strength, the connection M ispreferably forked, one end of the fork being placed on each side of thelug s. The other end of the connection M terminates in a ball u, Fig. 5,which is fitted between the cup-shaped ends u o of the crank-arm N,secured to the discharger-arm. The crank-arm is conveniently made in twopieces w w', secured together by the bolt w, and both being keyed orotherwise secured on the discharger'larm. A single key will serve tofasten both parts of the crank-arm to the IOO discharger-arm. It will beobserved rthat by .may be used independently of the other, or

that other mechanism for effecting either purpose may be substituted,while that herein shown for the other purpose is retained.

The discharger-arm A is bent or oset, as indicated at P, Fig. l, so thatwhen down, as

. indicated by the dotted lines A Fig. 2, it may clear theknotter-casing Q, or any projecting part thereon, as R. The extremity ofthe upward vibration of the discharger-arm is represented at A, Fig. 2,movement to about this position being sufficient to secure the dischargeof the bundle clear of the machine.

My improved bundle-discharger may be used in connection with anypreferred form of binding or knotting mechanism. In the accompanyingdrawings I have represented it as applied in connection with the bindingmechanism substantially similar to that shown in my pending application,Serial No.

The pivot B may be cast in onepiece with the support or bracket J.

The range of the movement of the discharger-arm is indicated by thedotted lines A A in Fig. 2, although it may be arranged to swing througha somewhat less angular distance, if desired.

The bundle-discharging mechanism may be operated either directly by thebinder-shaft D or by any other suitable arrangement.

It will be observed that by the construction herein shown I am enabledto entirely dispense with gearing, and that the connections hereindescribed are strong and durable and not liable to become clogged intheir operation by the straw.
